  • Software Layer for SIMCON ver. 1.1. FPGA-based TESLA Cavity Control System,
    2020
    Co-Authors: Krzysztof T Pozniak, Ryszard S Romaniuk
    Abstract:

    The paper describes design and practical realization of low and high level Software for laboratory purposes to control FPGA-based LLRF electronic equipment for TESLA. There is presented a universal solution for particular functional devices of the control system with FPGA chips. The paper describes architecture of Software Layers and programming solutions of hardware communication based on the proprietary Internal Interface (II) technology. Such a solution was used for the Superconducting Cavity Controller and Simulator (SIMCON) for TESLA experiment (Test Facility) in DESY. The examples of the build and tested Software blocks were given in this paper. This documentation is a unity with TESLA Reports published in 2004 by the Elhep and describing the SIMCON hardware, ver.1.0. The paper was written in a form of a User’s Manual.

  • Software Layer for fpga based tesla cavity control system
    Storage and Retrieval for Image and Video Databases, 2004
    Co-Authors: Waldemar Koprek, Pawel Kaleta, Jaroslaw Szewinski, Krzysztof T Pozniak, Tomasz Czarski, Ryszard S Romaniuk
    Abstract:

    A silver halide sensor type polymerizable light-sensitive material is disclosed. The material is comprised of a support having a silver halide photographic emulsion Layer and a polymerizing Layer adjacent to the emulsion Layer. The polymerizing Layer contains a nongaseous ethylenically unsaturated compound capable of undergoing addition polymerization upon reduction of the silver halide with a reducing compound. The material is capable of producing printing plates having good inking property and good printing durability. The material maintains the sensitivity and high resolving power of a silver halide photographic light-sensitive material.

  • ressd a Software Layer for resuscitating ssds from poor small random write performance
    ACM Symposium on Applied Computing, 2010
    Co-Authors: Seungryoul Maeng
    Abstract:

    NAND flash-based solid state drives have emerged as revolutionary storage media during recent years. However, the wide-spread of SSD technology is currently obstructed by the fact that the random write bandwidth is lower than the sequential write bandwidth by several orders of magnitude. This paper proposes a novel Software Layer called ReSSD whose purpose is to resuscitate SSDs from poor small random write performance with low memory usage. ReSSD works as a virtual block device on SSD which does not require any modifications of the operating system kernel and applications. By inspecting all incoming requests, ReSSD identifies small random writes which have potential to degrade SSD's performance significantly and transforms them into sequential and ordered-sequential writes which are more favorable to SSDs. Our evaluation results with Postmark show that ReSSD improves the overall performance by up to 72% using a few megabytes of kernel memory.

  • Enhanced Network Support for Federated Cloud Infrastructures
    IEEE Cloud Computing, 2016
    Co-Authors: Aniello Castiglione, Francesco Palmieri, Kim-kwang Raymond Choo
    Abstract:

    This article addresses the need for a new dedicated bandwidth paradigm that allows flexible orchestration of resources from different sites (for example, a manufacturing organization and its upstream and downstream vendors) joining a cloud without belonging to the same administrative domain (that is, it supports cross-domain operations and advanced network support). The main design goal is to turn the network communication capabilities into virtualized resources that can be scheduled in conjunction with more traditional cloud resources and managed by a specific Software Layer within the federated (manufacturing) cloud system services to implement a service plane for use by cloud applications and resource-management services.
